Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

Advanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Cat‐Vibrissa‐Inspired Biomass Fiber Aerogels for Flexible and Highly Sensitive Sensors in Monitoring Human Sport

Advanced Functional Materials, EarlyView.
Inspired by cat vibrissae, biomimetic biomass PHFs/SA aerogels (BFAs) are developed via precursor‐assisted in situ polymerization and freeze‐synergistic assembly. These ultralight, porous pressure sensors exhibit high sensitivity and excellent durability, enabling pulse detection, handwriting recognition, Morse code transmission, and notably real‐time ...

On‐Surface Indigo‐Based Bimolecular Coordination Networks with Programmable Regular or Vitreous Structure

Advanced Functional Materials, EarlyView.
A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...
